Assessing Your Mac's Capability to Handle Mac OS X

To minimize problems that you might experience installing or using Mac OS X, make sure that your Mac meets the following minimum requirements as stated by Apple:

  • Your Mac must be one of the following: Power Mac G4, Power Mac G4 Cube, Power Mac G3 (both the Blue and White and the original Beige models), PowerBook G3 (except the original PowerBook G3), PowerBook G4, iMac, or iBook.


    Although most iMacs and iBooks can run Mac OS X, if you have one of the original versions of either model, you might have trouble installing the OS, or if you are able to install it, it might not run very well. The original iMacs and iBooks are not really powerful enough (especially in terms of RAM) for Mac OS X. For example, a 233MHz or 266MHz G3 processor might not be fast enough to provide satisfactory performance for you. These machines came with only 32MB or 64MB of RAM, which is not adequate for Mac OS X.

  • At least 128MB of RAM.


    At press time, RAM was really inexpensive and providing 512MB of RAM could be done for only a few hundred dollars (less than $100 if you already have a couple hundred meg installed). Of course, your machine might not be able to take that much, but for all Macs, maximizing your Mac's RAM is one of the best investments you can make.

  • A video card that has a Mac OS X–compatible driver. If you have an Apple-supplied video card, such as an ATI or Nvidia graphics card (the standard cards in modern Macs, including the options on the Power Mac G4), you meet this requirement.

  • At least 1.5GB of free disk space.
